Sure.   Let's assume that you're running this process in an xterm (or 
equivalent) window.
I'm making the further assumption that you have a script or shell 
function that will effect
changes to an xterm window's title bar.  In case you don't, here's what 
I use:

xtitle ()
{
    echo -n -e "\033]0;$*\007"
}

So what you have to do is make sure these characters are directed to the 
right window.
Find the tty device you want by using `ps' or equivalent.  Say it's 
something like /dev/ttyp4.
Run the command with the desired arguments and redirect the output to 
/dev/ttyp4:

        xtitle 'long-running vim window' > /dev/ttyp4

If you like, you can put the filename vim's editing in there, too.
